I saw a thread from the old forums that was saying “Do not use the Male athletic body type” and other people were commenting, that if they used that command, they would have random characters popping up from the screen and they have to start their story from scratch. And other people commented that it won’t allow their story to be published? I’m so confused because I read two stories that had at least one character with the athletic body type?

It isn’t available anymore, but it used to give glitches.
I have a (unpublished) story in which one of my characters had the Athletic body and it would sometimes appear and then disappear, or other characters’ hair color would change to white.
